AUTO LIGHT SYSTEM

Component Parts and Harness Connector Location

AKS004JH

System Description

AKS004JI

Automatically turns on/off the parking lamps and the headlamps in accordance with ambient light.
Timing for when the lamps turn on/off can be selected using four modes.

OUTLINE

The auto light control system has an optical sensor inside it that detects outside brightness.
When the lighting switch is in “AUTO” position, it automatically turns on/off the parking lamps and the head-
lamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the set-
ting, Refer to 

LT-171, "SETTING CHANGE FUNCTIONS"

 .

Optical sensor, power is supplied

●

from BCM (body control module) terminal 45 

●

to optical sensor terminal 1.

Optical sensor, ground is supplied

●

from BCM (body control module) terminal 53 

●

to optical sensor terminal 3.

When ignition switch is turn to “ON” position, and
When outside brightness is darker than prescribed level, input is supplied

●

to BCM (body control module) terminal 38

●

from optical sensor terminal 2.

The headlamps will then illuminate. For a description of headlamp operation, Refer to 

LT-140, "System

COMBINATION SWITCH READING FUNCTION

Refer to 

LT-251, "Combination Switch Reading Function"

 .

EXTERIOR LAMP BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the AUTO position, and the ignition switch is turned from
ON or ACC to OFF, and one of the front door is opened, the battery saver control feature is activated.
Under this condition, the headlamp remain illuminated for 5mimutes, then the headlamp are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

SHUT OFF DELAY

When ignition switch is in the state of ON or ACC and a lighting switch is an AUTO position, after OFF and a
door switch (a driver, passenger) serve as ON from the state of ON of headlamp in an ignition switch, a head-
lamp is turned on for 5 minutes, and headlamp, parking lamp, and fog lamp are set OFF after that.
When a door switch (a driver, passenger) is turned on from OFF during 45 seconds or a 5 minute timer opera-
tion, the present timer stops, newly turns on a headlamp for 5 minutes, and sets headlamp, parking lamp, and
fog lamp to OFF after that. 
When a door switch (a driver, passenger) is turned off from ON during 45 seconds or a 5 minute timer opera-
tion, the present timer stops, newly turns on a headlamp for 45 seconds, and sets a headlamp, parking lamp,
and fog lamp to OFF after that. 
When an ignition switch is turned off from ON during the above mentioned timer operation, the function, which
stopped the timer and followed each lighting switch, is performed.
Shut off delay control mode can be changed by the function setting of CONSULT-II.

CAN Communication System Description

AKS004JJ

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
